Unity 3d 第一人称游戏开发表现怪异； 只能上下旋转

Question

im trying to make a first person game in unity, but I can only rotate up and down, and I was following a brackeys tutorial, and then I came across this error while programming it into my game.

using UnityEngine;



public class NewBehaviourScript : MonoBehaviour
{

    public float mouseSensitivity = 100f;

    public Transform PlayerBody;

    float xRotation = 0f;

    // Start is called before the first frame update
    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
    }

    // Update is called once per frame
    void Update()
    {
        float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
        float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        PlayerBody.Rotate(Vector3.up * mouseX);
    }
} 

Answer 1

Did you try looking up the documentation?

You are only rotating on the Z axis.

transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);

Also, why are you assigning the transform's localRotation and using the Rotate() method at the same time?
